CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 790,865, dated May 23,1905.

Application filed December 11, 1901. Serial No. 85,506.

To all whom, it may concern.-

Be it known that I, DANIEL ELMER AN- THONY, a citizen of the UnitedStates, residing at Akron, in the county of Plymouth and State of Iowa,have invented certain new and useful Improvements in Corn-Harvesters, ofwhich the following is a specification.

My invention relates to certain improvements in that class ofcorn-harvesters illustrated in Letters Patent granted to me January 1,1901, No. 665,301; and my invention consists in constructing andarranging the snapping-rolls of such a harvester as fully set forthhereinafter and as illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of a harvester embodying my improvements.-Fig. 2 is a rear elevation of sufficient to show the snapping-rolls andsupporting parts; Fig. 3, a rear perspective view of parts of the rolls,and

- Fig. 4 an end view of the rolls.

One of the characteristic features of my aforesaid patented invention isthe use of rearwardly-inclined rolls at the rear of the gatherers, oneof which rolls has a spiral groove of such a character that the rollsmay pass the standing corn without breaking or bending the same to anysubstantial extent, the corn being received by the grooves of the rollthe area of contact moving progressively upward as the rolls rotate andthe machine moves forward. In the said construction the spiral groovesare in one of the rolls, while the other roll has projections whichengage the stalks and tend to hold them in and feed them through thegrooves during said progressive action. My improvement consists insubstituting for the roll provided with projections for engaging thestalks a second grooved roll, the grooves in which, however, arereversely wound to those in the other roll, and the two rolls are soarranged that the ungrooved portions of one roll will be opposite thegrooved portions of the other roll, whereby the stalks may enter thegrooves of either roll with the same action as in my patentedconstruction except that in the present case the ungrooved portion ofeither roll will act in the same manner as the ungrooved roll in mypatented construction to hold the stalks in and feed them along thegrooves without breaking them. p

The rolls are arranged at the rear of the gatherers in a positioninclined somewhat from the vertical, and, as shown in the drawings,there are two rolls J K, each of which has continuous spiral grooves l l1, the grooves of each roll being opposite the ungrooved portions 3 3 ofthe other roll, and preferably there is formed upon these ungroovedportions teeth or projections which will aid in catching the stalks andfeeding them along the groovescduring the rotation of the rolls and theforward movement of the machine. As shown and preferred, these teeth orprojections are formed by roughening the surface of each roll betweenits grooves, so as to form comparatively small projections or teeth 2,like those of a coarsely-cut rasp; but they may be formed in any othersuitable way and be of any desired size.

The spaces between the grooves on either roll may be of any desiredwidth, and the grooves may be of any desired size and crosssectionalform, and the spirals may be of any required pitch or twist provided itis materially greater than the diameter of the rolls and of suchinclination to the angle of the rolls that the stalks when occupying aposition' in the grooves may stand substantially upright.

It will be seen that as the pitch of the spiral grooves is materiallygreater than the diameter of the rolls the latter may be arranged sonearly vertical as to act on but one or two hills of corn at a time withless friction than when the rolls are arranged approximately horizontaland act on a number of hills of corn at once. Further, the machine maybe driven forward more rapidly with a slower movement of the rolls thanwhen the latter are more nearly horizontal with the grooves of a pitchabout equal to the diameters of the rolls. The rolls are supported anddriven as in my aforesaid patented machine or in any other suitablemanner not necessary to be herein described.

By grooving both rolls I can increase the number of grooves, andconsequently take in a greater number of stalks at a revolution of therolls.

Without limiting myself to the precise construction and arrangement ofparts shown, 1 claim as my invention 1. In a corn-harvester, thecombination of the gatherers, and a pair of snapping-rolls inclinedupwardly and rearwardly and each provided with continuous unobstructedspiral grooves and the grooves in one being reversely wound to those inthe other, the ungrooved portions of one roll being opposite withoutextending into the grooved portions of the other roll, the angle ofinclination of the rolls being such that the engaging portions of thegrooves are substantially vertical, substantially as set forth.

2. In a corn-harvester, the combination of the gatherers, and a pair ofsnapping-rolls inclined upwardly and rearwardly and each provided withcontinuous unobstructed spiral grooves and teeth or projections on theungrooved portions, and the grooves in one being reversely wound tothose in the other, the ungrooved portions of one roll being oppositewithout extending into the grooved portions of the other roll, and theangle of inclination of the rolls being such that the engaging portionsof the grooves are substantially vertical, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

DANIEL ELMER ANTHONY.
